DOOR-CHECK.

SPECIFICATIN forming part of Letters Patent No. 652,982, dated July 3,1900. Application filed August 15, 1899. Serial No'7'727705. (No model.)

To all whom it may concern:

Be it known that LLOUIs H. SCHNEIDER, o New York, in the county of Kingsand State of New York, have invented certain new anduseful-'Improvements in Door-Checks; and I do hereby declare thatpthefollowing is a full, clear, and exact description thereof, referencebeing had to the' accompanying drawings, and to the letters of referencemarked thereon, which form' a part of this-'specification.

This invention relates to the devices contrived for the purpose ofholding the doors of dwellings, dac., open when desired; and it consistsof a plate having its upper vedge turned over to form a flange for thefoot and an opening made-in it, occupied by a stud and a spring to pressthe plate down and produce africtional engagement between the stud andplate, and an arm on the lower edge of the plate carrying afriction-block.

The invention is fully explained 'and illustrated in this specificationand the accompanying drawings.

Figure 1 shows a front elevation of the check attached to a'door. Fig. 2is a vertical cross-section of the device, taken on line 2 2 in Fig. l.Fig. 3 represents a top view of the check. Fig. 4 shows a perspectiveview of the center collar. Fig. 5is aperspective View of a detentenlarged. Fig. 6 is a perspective view of a spring enlarged. v

Similar letters of reference indicate the same parts in all the figures.

l The construction and operation are as folows: l

A is a plate, made, preferably, of sheet. metal,having a lange D turnedoutward at the upper edge at a right angle to the main plate. The lowerpart of the plate is carried down to 'form an arm J, which is broughtforward a little to clear the door and is bent out around at its end toform a clamp B to inclosle a polygon'al block of rubber F or some othermatel down as well as swing on the collar.

. screw N is putthrough the collar into the door to fasten it in place,and a flanged opening R is made in the plate to receive the collar G,the opening being made long enough vertically to allow the'plateAto moveup and The collar G has two recesses v fu made in its periphery, and acurved detent-plate E, Fig. 5, having a projection t, that lits' intothe recesses u on its upper side, is held in the opening R between thecollar G and a curved spring n, Fig. 6, which spring rests on the lowerside of the opening R to hold the plate A down with a yielding pressure.A segment of a circle L is attached to the door above the plate A bymeans of screws, and the inner part of the circle b is set oi from thedoor to allow the end of a clip c, attached to the back of the plate A,to slide under the part set o to help hold the plate in place.

The normal position of the check when not in use is shown by the dottedlines in Fig. 1,

and when used it is turned down into the position shown in full lines inthat figure by pressing on the end ofthe flange D, outside the segmentL, with the foot until the frictionblock F is in contact with the floorKand the projection t on the plate E is in the lowest recess fu in thecollar G and the door will be held stationary. When it is required thatthe door be closed, the plateAis thrown back i to its first position bypressing down with the foot on-the outer'end of the flange D ,until theprojection t is in the upper recess v and the friction-block F will beheld clear of the `loor and the door be free to move.

In a door-check the combination of a plate A having itshupper edgeturned over to form a flange for the foot, and an opening made in it, astud and a spring occupying said opening said. spring operative to pressthe plate down andproducingfrictional engagement between the stud andplate, an arm on the lower edge of the plate carrying a friction-block,substantially as described.

' In testimony whereof I have hereunto set my hand. this 9th day ofAugust, A. D. 1899.
